TO AIIL WHQM I T MYACONCERN:

Be it knojvn that I, Is'AA FISHER, of the city and county of St.-Lous, i n` the State ofblissouri, have invented a 'new and useful Improvement in Vjs'es; and I do hereby declare the following to be a full, clear, and

exact description thereof, suilicient to enable othersskilled in the art tofwhich the invention appertains to fully understand and use the same, reference being had to the accompanying drawings, which are made part of this "specification, and in which-'- Figurelis a front view ofa vise and bench illustrating my invention.

Figure 2 is a vertical section of the'same, the plane of section passing'lon'gitudinally through the horizoni tal axis, upon vvhich the vise' is supported and adjusted.

Figure 3 is a rear' view,'showiing'one ofthe bearings andthe horizontal axis of the vise. Similar letters of reference indicatecorresponding parts in the several figures. v Vises have hitherto been mounted upon a vertical axis to enable the Work griped between the jaws to be placed in the most convenient position to be operatednpon by the ile or whatever shaving, cutting, boring, 'or other tool- Inay be applied.v i This adjustment has been found practically insuilicient in many cases, and I have therefore devised a method offmounting the vise so as torender it adjustable yupon a horizontal as Well as a vertical axis, and I will new proceed. to explain the invention in detail.

In..the drawings, Amay represent a vise, which may be constructed in the usual manner, that'is to say, with twojaws actuated by a screw, on after anyof theimproved plans thatmay exist. I providethe vise Wi'th'the customary vertical axi'sQB, vupon-Which said vise may. be swung' around in a li'oriz'ontal plane, and the threaded end f theaxisB has ajaw-nut, C, whereby the vise'may be'rigidly retained in any positionto which it maybe thus moved. i

While the vise isadapted by the axis B to be turned in-.a horizontal plane, as above described, it is supported by the seat D, of which the ar-xnD" is a part orcontinuation. The arm Dv is joined at its centre tothe horizontal axis E, one oftyhose bearings is supplied by the semieircular plate F, whichis rigidlyattaehed t'o thebench'Gr. 'The after-bearing is seen at F.." The free extremity of the-arm D carries a clamp, H, movable by means of the handle L, so as to be made to clamp or releasethe rim of the plate F, with which latter the. axisA of the. arm D 'is concentric.

The horizontal axis `E enables the vise A to4 be adjusted in a'vertical plane, gis-clearly shown by red lines in iig. 1, and the vise, when moved under this adjustment, maybe retained rigidly in the desired position by thel clamp H.- v y i I y The two axes B and E enable the position .of the vise to be varied to suchen extent and with such facility that the operator may work with the greatest convenience, withoutreleasing the Workk from the jaws, andhe may also move the viselas may be requred'tobring the W'orkwithin the range ofthe light.

' Theseat D, arm D', and axis E are designed to constitute but a; single casting.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isf- The improvedvise'A, the same having two axes or centres of adjustment, arranged substantially as described.

The above, sighed on this 6th day of Apntises.' Y, j Y ISAAC FISHER. Witnesses: l
